// Arduino side code for data acquisition
// Assume Arduino connected to 4 Sensors ,On receiving appropriate characters,Arduino sends back Sensor values

// @ -> will trigger TransmitHumidityValue();       -> will send back humidity value
// # -> will trigger TransmitSoilMoistureValue();   -> will send back Soil-Moisture value
// $ -> will trigger Transmit_Temperature_Value();  -> will send back Temperature Value
// & -> will trigger TransmitLightIntensityValue(); -> will send back Light Sensor Value

// Functions are standin and user is supposed to implement them according to their needs 
// For Demo, the functions send a random number.
